Implement the given UML. You have one interface called '_Area' and one abstract class called '_Shape'. Class '_Shape' will be used as a super class. Overide the methods toString, getArea and getName in all classes.

The area of the circle and triangle:

Circle Area = pi *r^2 Triangle Area = 0.5 * height * base

make a test class and . Make objects from class Circle , Triangle. Then assign all objects to array of type _Shape, iterate over the array and call toString of each object.

The out put should be like:

Class name is circle

Area =

Class name is triangle

Area=
